Self-interacting dark matter
In astrophysics, self-interacting dark matter (SIDM) is a hypothetical form of dark matter consisting of particles with strong[clarification needed] self-interactions. This type of dark matter was postulated in 2000 to resolve a number of conflicts between observations and simulations (of collisionless cold dark matter) on the galactic scale and smaller. It was also used to explain the 2015 observations of ESO 146-5 the core of the Abell 3827 galaxy cluster.
- MACS J0025.4-1222, astronomical observations that constrain DM self-interaction
- ESO 146-5, the core of Abell 3827 that was claimed as the first evidence of SIDM
- Strongly interacting massive particle (SIMP), proposed to explain cosmic ray data
